[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The high-pressure flushing-resistant temperature and humidity sensor protection device for this experimental animal facility is equipped with a fixed chamber, a rotating chamber, a shock-absorbing structure, and a ventilated structure. A drainage channel at the top of the rotating chamber guides the impacting water flow, dispersing its force. When the rotating chamber closes to the surface of the fixed chamber, two sealing gaskets, one inside and one outside, seal the gap between the rotating and fixed chambers and prevent water from seeping into this gap through a chute, ensuring excellent sealing performance. A spring damper absorbs the vibrations generated by the water flow impact on the rotating chamber, preventing damage to the sensor. Heat dissipation fins and a heat spreader enhance the sensor's heat dissipation during use. The combination of the fixed plate, waterproof and breathable membrane, and partition allows the sensor to communicate with the outside environment through a ventilation pipe while preventing water from entering the fixed chamber through the ventilation pipe. This results in a temperature and humidity sensor with good sealing performance, strong resistance to water flow impact, and a certain degree of shock absorption, balancing waterproofing and breathability.

[0014] 2. The high-pressure flushing resistant temperature and humidity sensor protection device for this experimental animal facility is equipped with a hinge and locking structure. The rotating chamber rotates on top of the fixed chamber via the hinge, facilitating the opening and closing of the rotating chamber. When the rotating chamber is closed on top of the fixed chamber, the top of the insertion rod is inserted into the slot under the action of the return spring. Since the insertion rod interferes with the slot, the rotating chamber cannot be opened at this time, thus initially fixing the rotating chamber and the fixed chamber. The sealing gasket is inserted into the slide groove to provide a certain degree of waterproof performance. The rotating chamber and the fixed chamber are then fixed by the spring buckle. The sealing gasket is removed, and the lever is pushed down to move the top of the insertion rod out of the slot, allowing the rotating chamber to be opened and closed. This makes the temperature and humidity sensor easy to disassemble and convenient for maintenance. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A high-pressure rinsing-resistant temperature and humidity sensor protection device for laboratory animal facilities includes a base plate 1. A fixed chamber 2 is fixedly connected to the top of the base plate 1. A slide groove 21 is provided on one side of the fixed chamber 2. A rotating chamber 3 is movably connected to the top of the fixed chamber 2. A hinge 4 is fixedly connected to the side of the fixed chamber 2 and the rotating chamber 3 away from the slide groove 21. A drainage groove 31 is provided on the top of the rotating chamber 3. A sealing gasket 32 ​​and a sealing gasket 33 are fixedly connected to the bottom of the rotating chamber 3. A slot 34 is provided at the bottom of the rotating chamber 3. A shock-absorbing structure 5 is provided at the bottom of the rotating chamber 3. The shock-absorbing structure 5 includes a mounting plate 51. A spring damper 52 is fixedly connected to the top of the mounting plate 51. A heat dissipation fin 53 is fixedly connected to the top of the mounting plate 51. A heat-spreading plate 54 is fixedly connected to the surface of plate 53. A circuit board 55 is fixedly connected to the bottom of mounting plate 51. A locking structure 6 is provided inside the slide 21. The locking structure 6 includes a return spring 61. A plug rod 62 is fixedly connected to the top of the return spring 61. A lever 63 is fixedly connected to the surface of the plug rod 62. A sealing gasket 64 is inserted into the inside of the slide 21. A ventilated structure 7 is provided on the surface of the fixed chamber 2. The ventilated structure 7 includes an air exchange pipe 71. A fixed plate 72 is fixedly connected inside the air exchange pipe 71. A waterproof and breathable membrane 73 is fixedly connected to the surface of the fixed plate 72. A partition 74 is fixedly connected to the surface of the waterproof and breathable membrane 73. The fixed chamber 2, rotating chamber 3, shock-absorbing structure 5, and ventilated structure 7 are provided. The flow channel is located at the top of the rotating chamber 3. 31 guides and disperses the impact force of the water flow. When the rotating chamber 3 closes on the surface of the fixed chamber 2, the sealing gaskets 32 (inner) and 33 (outer) seal the gap between the rotating chamber 3 and the fixed chamber 2, and prevent water from seeping into the gap between the rotating chamber 3 and the fixed chamber 2 from the sliding groove 21, resulting in good sealing performance. The spring damper 52 absorbs the vibration generated by the water flow impact on the rotating chamber 3, preventing it from affecting the sensor. The heat dissipation fins 53 and the heat spreader 54 increase the heat dissipation effect of the sensor during use. The cooperation of the fixed plate 72, the waterproof and breathable membrane 73, and the partition 74 allows the sensor to communicate with the outside world through the ventilation pipe 71 while preventing water from entering the fixed chamber 2 from the ventilation pipe 71. This design ensures the temperature and humidity sensor has good sealing performance, strong resistance to water flow impact, and a certain degree of shock absorption, while also balancing waterproofing and breathability. A hinge 4 and a locking structure 6 are incorporated. The rotating chamber 3 rotates on top of the fixed chamber 2 via the hinge 4, facilitating its opening and closing. When the rotating chamber 3 is closed on top of the fixed chamber 2, the top of the insertion rod 62 is inserted into the slot 34 under the action of the return spring 61. Because the insertion rod 62 interferes with the slot 34, the rotating chamber 3 cannot be opened at this time, thus initially securing the rotating chamber 3 and the fixed chamber 2. The sealing gasket 64 is then inserted into the slide groove 21, providing some waterproofing. Finally, the rotating chamber 3 and the fixed chamber 2 are secured by a spring-loaded latch. The sealing gasket 64 is then removed.Pushing the lever 63 downwards moves the top of the insertion rod 62 out of the slot 34, allowing the rotating chamber 3 to be rotated and opened, making the temperature and humidity sensor easy to disassemble and maintain.

[0024] Furthermore, mounting bases are fixedly connected to both sides of the base plate 1, and the base plate 1 is fixedly connected to the wall through the mounting bases. Spring buckles are provided on the surfaces of the fixed compartment 2 and the rotating compartment 3, and the fixed compartment 2 and the rotating compartment 3 are fixed by the spring buckles. The spring buckles are existing technology and will not be described in detail hereafter.

[0025] Furthermore, the sealing gasket 32 ​​and the sealing gasket 33 are U-shaped. The length and width of the sealing gasket 32 ​​are both greater than those of the sealing gasket 33. The top of the fixed chamber 2 has two sets of grooves. The sealing gasket 32 ​​and the sealing gasket 33 are respectively connected to the two sets of grooves. The sealing gasket 32 ​​and the sealing gasket 33 are both made of rubber. With the sealing gasket 32 ​​and the sealing gasket 33 set inside and outside, the gap between the rotating chamber 3 and the fixed chamber 2 can be sealed, and water can be prevented from seeping into the gap between the rotating chamber 3 and the fixed chamber 2 from the sliding groove 21. The sealing performance is good.

[0026] Furthermore, the bottom surface of the diversion channel 31 is inclined, and six sets of diversion channels 31 are symmetrically arranged. The diversion channels 31 set on the top of the rotating chamber 3 guide the impacting water flow and disperse the impact force of the water flow.

[0027] Furthermore, the spring damper 52 is bolted to the bottom of the rotating chamber 3, the heat dissipation fins 53 are in contact with the top of the circuit board 55, and the top of the heat spreader 54 is not in contact with the bottom of the rotating chamber 3. The spring damper 52 absorbs the vibration generated when the rotating chamber 3 is impacted by water flow, preventing it from affecting the sensor. The heat dissipation fins 53 and the heat spreader 54 increase the heat dissipation effect of the sensor during use.

[0028] Furthermore, the top of the insertion rod 62 is inserted into the slot 34, and the two ends of the return spring 61 are fixedly connected to the bottom of the slide groove 21 and the bottom of the insertion rod 62, respectively. The surface of the sealing pad 64 is provided with a square groove that matches the lever 63. The sealing pad 64 is made of rubber. The rotating chamber 3 is rotated on top of the fixed chamber 2 via the hinge 4, which facilitates the opening and closing of the rotating chamber 3. At the same time, when the rotating chamber 3 is closed on top of the fixed chamber 2, under the action of the return spring 61, the top of the insertion rod 62 is inserted into the slot 34. Since the insertion rod 62 will interfere with the slot 34, the rotating chamber 3 cannot be rotated open at this time. Thus, the rotating chamber 3 and the fixed chamber 2 can be initially fixed. The sealing pad 64 is inserted into the slide groove 21, which can provide a certain degree of waterproof performance for the slide groove 21. The sealing pad 64 is removed, and the lever 63 is pushed down to move the top of the insertion rod 62 out of the slot 34, so that the rotating chamber 3 can be rotated open and closed.

[0029] Furthermore, the surface of the fixing plate 72 is provided with round holes, and the surface of the partition plate 74 is provided with multiple sets of honeycomb-shaped vent holes. The inside of the vent holes is provided with a hydrophobic coating. Through the cooperation of the fixing plate 72, the waterproof and breathable membrane 73 and the partition plate 74, the sensor can communicate with the outside world through the ventilation pipe 71 while preventing water from entering the fixing chamber 2 from the ventilation pipe 71. The waterproof and breathable membrane 73 is existing technology and will not be described in detail hereafter.

[0030] Working principle: In use, the base plate 1 is fixedly connected to the wall via the mounting bracket. The rotating chamber 3 rotates on top of the fixed chamber 2 via the hinge 4, facilitating the opening and closing of the rotating chamber 3. Simultaneously, when the rotating chamber 3 is closed on top of the fixed chamber 2, the top of the insertion rod 62 is inserted into the slot 34 under the action of the return spring 61. Since the insertion rod 62 interferes with the slot 34, the rotating chamber 3 cannot be opened at this time, thus initially fixing the rotating chamber 3 and the fixed chamber 2. The sealing gasket 64 is then inserted into the slide groove 21, providing some waterproofing. The rotating chamber 3 and the fixed chamber 2 are then fixed by the spring latch. Removing the sealing gasket 64 and pushing the lever 63 downwards moves the top of the insertion rod 62 out of the slot 34, allowing the rotating chamber 3 to rotate and open, thus enabling the temperature and humidity sensor to operate. The sensor is easy to disassemble. The water flow is guided by the drainage groove 31 on the top of the rotating chamber 3, which disperses the impact force of the water flow. When the rotating chamber 3 is closed on the surface of the fixed chamber 2, the sealing gaskets 32 and 33, which are set inside and outside, can seal the gap between the rotating chamber 3 and the fixed chamber 2 and prevent water from seeping into the gap between the rotating chamber 3 and the fixed chamber 2 from the sliding groove 21. The sealing performance is good. The spring damper 52 absorbs the vibration generated by the water flow impact on the rotating chamber 3 and prevents it from affecting the sensor. The heat dissipation fins 53 and the heat spreader 54 increase the heat dissipation effect of the sensor during use. The cooperation of the fixed plate 72, the waterproof and breathable membrane 73 and the partition 74 allows the sensor to communicate with the outside world through the ventilation pipe 71 while preventing water from entering the fixed chamber 2 from the ventilation pipe 71.
